John Cassidy of Earthquakes Canada says the relatively small quake occurred just after 3 p.m.
It's one of thousands of aftershocks that have been occurring since a 7.7-magnitude quake hit the region last fall.
The seismologist says he's received a couple of reports that the quake was lightly felt in Skidegate and the Village of Queen Charlotte, but most people went about their day without disruption.
The quake struck about 91 kilometres west of Queen Charlotte City, B.C.
Cassidy says the quake was too small to have caused any damage or injuries, and people shouldn't be worried.
The 7.7 earthquake that rocked Haida Gwaii in October was the strongest recorded in Canada since 1949.
